Change Details

I was exploring `wdt:P594` when I realized that queries like the following one does not return a stable result but they vary between true and false (probably depending on the server(s) they hit):
```sparql
ASK WHERE
{
wd:Q18047295 wdt:P594 ?ensembl.
wd:Q18047295 p:P594 ?statement .
?statement ps:P594 ?ensembl .
}
```
It's pretty weird, since that should be the standard Wikidata data pattern. Seems like it's happening again the issue described in T112397
Edit: @Gstupp fixed `wd:Q18047295` with a manual editing (see here: https://github.com/SuLab/scheduled-bots/issues/22)
Other possible affected items:
```sparql
SELECT * WHERE
{
?item wdt:P594 ?ensembl .
FILTER NOT EXISTS {
?item p:P594 ?statement .
?statement ps:P594 ?ensembl .
}
}
```
A couple of questions:
* Is it a general inconsistent state of Wikidata or is it happening just for a subset of items (e.g., those updated with bots)?
* Is there a way to detect, to fix and - even better - to avoid those inconsistencies?
Thank you guys!
